MUSIC-BOX.

SPECIFICATION forming part of Letters Patent No. 460,253, datedSeptember 29, 1891.

Application filed Jannary`9, 1890. Serial No. 336.453. (No model.)Patented in Switzerland May 29, 1889, No. 997.

To all whom, t may concern.-

Be it known that I, EMILE .IACOARD-MAR- GOT, a citizen of the HelveticConfederation, residing in the town of St. Croix, Switzerland, haveinvented certain new and Improved Musical Boxes, (for which I haveobtained a patent in Switzerland, No. 997, bearing date May 29, 1589,)of which the following' is a fpecilication.

My invention relates to improvements in musical boxes, and of which thefollowing is a full and exact description.

In the accompanying' drawings, Figure l is a top view or plan ofmyimproved musical box with the lid removed. Fig. 2 is a section on theline a b in Fig. l. Fig. 3 is an elevation of the ily-wheel.

My improved musical box is composed, principally, of a clock mechanism,which transmits rotary movement to the musical drum A. The drum B, inwhich the spiral or main spring is located, transmits its movement tothe drum A by means of the gear-wheels C and D and the arm E into arecess, in which a button or stud F, firmly fixed to or of one piecewith the musical drum, penetrates said drum, carrying two centers orpoints G G arranged in appropriate bearings. The toothed wheel D, Fig.2, turns on a socket or sleeve H, made of one piece with the bearing,I', and is retained in the same by a screw J runningin a groove in thesleeve I'I, so as to preventall movement of the said wheellongitudinally to the socket, but allow the same to rotate freely. Thetoothed wheel I, made of one piece with the wheel D, is provided with astud K, which, at each revolution, lifts a lever L, pivotally arrangedin the bearing M and operating a pawl N, gearing into the ratchet-wheelO, Figs. l and 2, attached to the cam O. This cam is provided withrecessed and projecting parts and turns freely on the sleeve I'I, whichis provided with a longitudinal slot Q for receiving a pin or peg S,fixed in the spindle I), running through the said sleeve H. A spiralspring R is arranged around the outer end of spindle P, has the tendencyto push the same in the direction of the arrow, Eig. 2, and

causes the extremity of the peg S to be continuously pressed against therecessed surface of the cam O.

The spindle I) has a longitudinal movement, which depends on the rotarymovement of the cam, said longitudinal movement being transmitted to thedrum A, one ot the points G being' carried in the bearing in the extremeend of the spindle P, which produces the change in the tune or melody.The other extremity G' of the drum A rests in the bearing T in a spindleU, surrounded by a spiral spring and carrying' a pin V, the said springhaving the tendency to press the spindle in the direction of the arrow,Fig, l.

For releasing or lixing the drum A it is sutlicient to give the key IV aquarter of a turn, which said key operates on the pin V and presses thespindle U to the rear. The gearwheel I transmits movement to a fly-wheelgovernor X by means of the toothed wheels a l) and the worm C.

The device, as represented in Fig. 3, is formed ot' two wings, onemovable and the other a Iixture. The movable wing carries a fork e,attached at its extremity to a screw (Z, which serves to regulate theoperation of the fly or wing, which also acts as brake by means of theaugmentation ot' the resistance of the air. The regulation can beeffected during the playing ot' the music and without stopping the same.The change of the airs can be made automatically at each revolution bymeans of the cam O', which is rotated one step by the pawl N, and therecessed or shouldered surface of which acts on pin S to move the drum Alongitudinally and bring' into place the devices adapted to produceanother tune. The airs can also be changed, when desired, independentlyof stud K and lever L, and it suffices to operate the lever f, Eig. l,which acts on the pawl N and the ratchet-wheel O. Another lever g servesto place the pawl N out of contact with the wheel O during the playingwhen it is desired to continue playing the same air.

In order to arrest the apparatus, the lever L must be operated, whichlifts the piece l, against which a rod m abuts, said rod being of onepart with the fly-wheel regulator or governor and serving to arrest thesame, and consequently the whole mechanism. This stopping can only beeffected when the drum A has made a complete revolution, the part Zbeing provided with a rod q, which can enter the recess in the wheel Iand only come in contact with the same at eaeh revolution of the wheel.The cam O can be arranged on the end of the spindle in a specialbearing, if so desired.

Having now particularly described the nature of my said invention and inwhat manner the same is to be performed, what I claim 1. In a music-box,the combination, with the pin-drum, comb, and drive mechanism for thedrum, of the cam Wheel mounted loosely on the drum-spindle, mechanicalconnections between the cam-wheel and driving` mechanism, whereby thesame is rotated, and a pin controlling1 the longitudinal position of thedrum with relation to the comb, bearing against said cam, substantiallyas described.

2. In a music-box, the combination, with the pin, longitudinallymovabledrum, comb, and drive mechanism for the drum, of the lon gitudinally-movable spindle having a bearing therein for the drum at one end, thecamwheel journaled loosely on said spindle, a pin on the spindle,bearing against the cam, and mechanical connections between the cam anddriving mechanism, whereby the same is rotated intermittingiy,substantially as described.

3. In a music-box, the combination, with the pin, longitudinally-movabledrum, comb, and drive mechanism for the drum, of the cam journaled onthe drum-spindle and en' gaging a pin thereon, a ratchet-wheel connectedto said cam, a pawl moved by the driving mechanism and engaging saidratchet-Wheel to rotate the cam,and the pin on the spindle,substantially as described.

4E. In a governor for the driving mechanism of music-boxes, thecombination, with the rotary ily-fan rotated by the driving mecl1-anism, of the non-rotary fan adjustable toward and from the rotary fan,whereby the speed of the same may be regulated, substantially asdescribed.

5. The combination, with the drum A, of the actuating mechanism, thefly-governor X, connected with said mechanism, the non-rotary member,andthe regulating screw LZ, substantially as described.
